How to Blur Background for Vertical Video in iMovie

Add a blurry background to fill sides of your vertical video can help you enhance the viewer's engagement and make your videos more captivating. However, there is no a official blur filter/effect in iMovie for you to blur your vertical video background.

But luckily, here is a workaround of blurring the background and fill in the sides of vertical video in iMovie which involves using the great title feature called "Pull Focus".

Now, let's get into the detailed steps of achieving the blurred background vertical video in iMovie.
